Diamond Education

When people start learning about diamonds, the conversation often turns technical very quickly. Charts, grades, and reports are useful tools, but they are not always helpful on their own. Diamonds do not live on paper. They are worn and seen in motion, under different light, in the context of a finished ring.

At Alexis Gallery, this is all part of the conversation from the start of your journey. We use it to explore options, talk through tradeoffs, and make choices that feel right for the overall appearance of your finished ring.

We made this guide to share the questions we talk through most often with clients as they design custom engagement rings and wedding rings with us.

The 4 C’s of Diamond Quality

The 4Cs, cut, colour, clarity, and carat weight, give us a shared language for talking about diamond characteristics. They describe measurable specifications for the visual properties. When used thoughtfully, they help bring clarity to decisions. When treated too rigidly, they can get in the way of good design.

Diamond Cut: How a Diamond Handles Light

Cut describes the diamond’s brilliance, which is measured by its symmetry and polish. It plays a major role in how light moves through the stone and how that light returns to the eye. A well cut diamond feels balanced and sparkles. A poorly cut diamond loses light, even if other grades are high.

Diamond Colour: Perception Depends on Context

Colour grading measures the natural warmth (ie. yellow) in a diamond. The closer a diamond is to D, the less colour there is in the stone.

Diamond Clarity: Visibility Over Classification

Clarity refers to internal characteristics, also known as inclusion, that formed as a diamond grew. For most diamonds, these are only visible under magnification and are invisible to the naked eye.

Diamond Carat: Weight is Only One Factor

Carat weight measures how much a diamond weighs, not how large it appears. Two diamonds with the same carat weight can look quite different depending on cut depth, shape, and proportion. Setting design also plays a role in how present a stone feels.


We treat carat weight as one design input among many, always considering it alongside proportion and overall balance.

Lab Grown and Earth Mined Diamonds

Origin, Not Structure

We often start this conversation by clearing up a common misconception. Lab grown and earth mined diamonds are both real diamonds. They share the same chemical composition, crystal structure, optical properties, and hardness. The difference is where they come from.

Earth mined diamonds are formed naturally beneath the earth’s surface over geological time. Lab grown diamonds are created in controlled environments that replicate diamond forming conditions.

Both are graded using the same international standards.

Why Clients Choose Lab Grown Diamonds

Many of our clients are drawn to lab grown diamonds because of the flexibility they offer. Accessible pricing and availability can open up more options when balancing size, cut quality, and design direction. Some clients also appreciate knowing more about how and where their diamond was produced.

We work with lab diamonds every day, offering them as centre stones for custom engagement rings and pairing them with lab grown melee to ensure a consistent stone origin in a design.

Why Clients Choose Earth Mined Diamonds

Other clients are drawn to earth mined diamonds for their geological origin and long history in fine jewellery. For some, that connection to natural formation carries personal meaning. We source earth mined diamonds that meet recognized ethical and conflict free standards and incorporate them into custom designs across a wide range of shapes and styles.

Diamond Shapes and Visual Behavior

Commonly Requested Shapes

We design with many different diamond shapes, each bringing its own character to a ring. Round diamonds distribute light evenly and feel timeless. Oval diamonds emphasize length and movement. Emerald cuts draw attention to symmetry and internal structure. Pear shapes introduce asymmetry, while cushion cuts soften geometry without losing definition. You can also get less traditional shapes through our custom cutting process if you’re looking for something more unique.
Diamond shape is arguably the most influential role in your ring design.

How Diamond Cut Influences Light

Different shapes interact with light in different ways. Brilliant cuts break light into smaller reflections that feel lively and dynamic. Step cuts create broader flashes and place more focus on clarity and structure. These patterns come intentionally from how a diamond is cut and what type of sparkle is being emphasized.

Diamond Colour as a Design Element

We enjoy working with colour as part of the design conversation. Subtle champagne, pale yellow, or grey diamonds can add warmth and personality without overpowering a setting. In these designs, colour is something we build around rather than correct.

Certified Diamond Pricing in Custom Work

What Influences Cost

Diamond pricing reflects a combination of cut quality, carat weight, colour, clarity, origin, and market availability. Small changes in proportion or grading can affect the cost, and for most people, not create a noticeable difference once a diamond is set.

Our goal is always to maximize your budget without compromising on quality. For those with very narrow specifications in mind, we can work within them.  Otherwise, our ‘secret sauce’ allows us to balance quality and budget to ensure a diamond that is clear, white and brilliant (if that’s your goal).

Stone and Setting Work Together

A diamond never exists on its own. Band width, metal choice, and structural design all shape your finished ring. That is why we talk about your stone and setting together from the beginning.

How Pricing Is Discussed

Budgets are discussed early and clearly.  If your budget aligns with your request, we will maximize it to its fullest potential.  If it doesn’t, we’ll provide suggestions on what will stay within your limits.

Final pricing is provided during your design meeting based on your curated stones.

Ethics and Sourcing at Alexis Gallery

Material Selection

We work with responsibly sourced lab grown and earth mined diamonds and prioritize recycled precious metals whenever possible. 

Craft and Community

We craft every ring in Toronto from start to finish. Keeping our work local gives us a deeper connection to the making process and to the people behind it, shaping how we approach quality, care, and collaboration.

Longevity as a Design Principle

When a ring is meant to be worn every day, comfort, durability, and secure settings matter. We educate clients to make the best and most long-lasting design choices bridging their design vision and their lifestyle.

Buying Diamonds with Clarity

Diamond education is most useful when it moves beyond theory and spreadsheets and into real decisions. Seeing stones side by side, adjusting proportions, and refining design details are all important steps in the process.

At Alexis Gallery, we work this into every step of the process. Every custom engagement ring and wedding ring takes shape through thoughtful curation, collaborative design, and in-house craftsmanship, with each choice considered in the context of the finished piece.

If you would like to review diamonds, explore settings, or begin a custom project, we would be happy to talk. A phone consultation is an easy, focused way to start the process and begin shaping something personal.
